zookeeper+openfeign远程调用

Posted 2022-12-15 isTrueLoveColour

首先确保zookeeper集群可用

所需依赖为：

	<dependencies>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-zookeeper-discovery</artifactId>
        </dependency>

     <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-openfeign</artifactId>
        </dependency>


        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
    </dependencies>

服务1配置文件

server:
  port: 9010



spring:
  application:
    name: zkServer1
  cloud:
    zookeeper:
      connect-string: 192.168.158.158:2181,192.168.158.159:2181,192.168.158.160:2181

服务2配置文件

server:
  port: 9020



spring:
  application:
    name: zkServer2
  cloud:
    zookeeper:
      connect-string: 192.168.158.158:2181,192.168.158.159:2181,192.168.158.160:2181

服务启动类

@SpringBootApplication
//开启openfeign
@EnableFeignClients	
//向zookeeper注册
@EnableDiscoveryClient
public class ZookeeperApplication 
    public static void main(String[] args) 
        SpringApplication.run(ZookeeperApplication.class, args);
    

服务1代码

@RestController
@RequestMapping("/zk1")
public class ZkController 

    @Autowired
    private ZkFeignService zkFeignService;

    @GetMapping("/zk1return")
    public String zk1return()
        return "服务2调用1成功";
    


    @GetMapping("/test")
    public String test()
        return zkFeignService.test();
    

@Component
@FeignClient(value = "zkServer2")
public interface ZkFeignService 

    @GetMapping("/zk2/zk2return")
    public String test();

服务2代码

@RestController
@RequestMapping("/zk2")
public class ZkController 

    @Autowired
    private ZkFeignService zkFeignService;

    @GetMapping("/test")
    public String test()
        return zkFeignService.test();
    

    @GetMapping("/zk2return")
    public String zk1return()
        return "服务1调用2成功";
    

@Component
@FeignClient(value = "zkServer1")
public interface ZkFeignService 

    @GetMapping("/zk1/zk1return")
    public String test();

然后两个服务就可以通过指定接口相互访问
